Javascript Callback in Mozilla firefox.

Problem with javascript code in Mozilla firefox.

[CODE]
[COLOR=”red”]//Initial Code block[/COLOR]
PhaseID = cboPPPhase.options[cboPPPhase.selectedIndex].value;
WorkflowRequest(PhaseID);

[COLOR=”Red”]//The function[/COLOR]
function WorkflowRequest(PhaseID)
{
[COLOR=”red”] //This is Ajax code block[/COLOR]
Http.get({url: “../ajax/Process.aspx?PhaseID=” + PhaseID , asynchronous:false, callback: WorkflowRequest_callback});
}

[COLOR=”Red”]//The callback function[/COLOR]
function WorkflowRequest_callback(Result)
{
if (Result.readyState==4)
{
if (Result.status==200)// if “OK”
{
WorkflowProcessResult(Result);
}
}
}

[/CODE]

The problem here is that after calling the ajax code i cannot able to call the callback function (WorkflowRequest_callback(Result). The debugger does not come to the call back function.
[COLOR=”red”]This occurs in Mozilla browser and works perfectly in IE.[/COLOR]

[CODE]
 get: function(params, callback_args){
if (!Http.enabled){
//alert("Http: XmlHttpRequest not available.");
return null;
}

var url = params.url;
if (!url)
{
//alert("Http: A URL must be specified");
return null;
}

var method = params.method || Http.Method.Get;
var callback = params.callback;
var async = params.asynchronous;
//alert(async);
if (async == undefined)
async = Http.Asynchronous;

//alert('method : ' + method + "nn" + 'url : ' + url + "nn" + 'async : ' + async)

//alert(async);

var sep = (-1 < url.indexOf("?")) ? "&" : "?"
url = url + sep + "__=" + encodeURIComponent((new Date()).getTime());

// Only one request at a time, please
if ((Http._get.readyState != Http.ReadyState.Uninitialized) &&
(Http._get.readyState != Http.ReadyState.Complete)){
this._get.abort();
}
alert(method +" Url "+ url+" Async "+ async);
Http._get.open(method, url, async);



[COLOR="Red"]Http._get.onreadystatechange = function() {
if (Http._get.readyState != Http.ReadyState.Complete) return;

if (callback_args == null) callback_args = new Array();

var cb_params = new Array();
cb_params.push(Http._get);
for(var i=0;i<callback_args.length;i++)
cb_params.push(callback_args[i]);

if ( callback!=null)

//alert(params.body);

//if (params.body)
//alert(params.body);
Http._get.send(params.body || null);

}

@willfindavidauthorJul 14.2008 — I think the error is somewhere here in the Ajax code coloured red.

In IE the Ajax code executes peoperly but in Mozilla the code doesnot execute.
